Kelsea Ballerini is getting married soon, and she's doing her bachelorette weekend up right with a trip to Vegas that includes hanging with Jennifer Lopez.

The excited singer kicked things off with a post to Instagram on Friday (Sept. 16), sharing a video of herself on board a plane goofing around and singing, "I'm ready to party with the best of 'em!" in a comical voice.

She shared a photo of herself and her squad, and they all hit Lopez' All I Have residency at the AXIS auditorium at Planet Hollywood Resort & Casino, where they playfully struck a wacky pose with Lopez herself in front of the event poster on the red carpet.

Ballerini posted a shot of herself with Lopez that she captioned, "Don't be fooled by the rock(s) that I got," and also posted another shot of herself smiling and looking content, with her engagement ring prominently on display.

“We are so focused on music, and I think meeting each other and falling super in love with each other was a big surprise for both of us,” Ballerini says (quote via Nash Country Daily). "And I think we’re kinda like … we’re so stoked to get married, but the actual wedding part isn’t really what we care about."

The singer is gearing up to release a new album, Unapologetically, on Nov. 3, so it's been a relief to be able to leave the wedding plans in such capable hands.

" ...She’s amazing," Ballerini says. "I was like, 'I want this amount of people and I don’t want it to be in Nashville or Australia. I want it to be neutral. And we’ll be there.' It’s at the end of the year, and we’re both gonna keep, you know, sprinting until then and then get married and take December off."
